I wouldn't pay for it anyway, no job really needs it unless for some reason you continuously fight something that uses earth and lightening elemental spells and there's no way you can kill it without this O.o

But yeah that quest is really only good for fame. And I'll just NPC this earring, I doubt it goes for much or sells very fast.

lmao... it's not like every quest gives you something good. What about the quests that give you 500 gil? It's not like you can DO anything with only 500 gil, but they have to give you SOMETHING in return. I don't think anyone wears these anyways XD
